Fig. 2 is the plane graph illustrating the display floater 110 according to illustrative embodiments, and
Fig. 3 is the zoomed-in view of the part " A " illustrating Fig. 2.
With reference to Fig. 2 and Fig. 3, include having according to the display floater 110 of illustrative embodiments
Round-shaped viewing area DA and the non-display area being positioned at around the DA of viewing area
NDA。
It addition, viewing area DA include wherein hierarchic structure sightless central area CP and
Wherein hierarchic structure visible marginal area EP.
Viewing area DA includes being arranged in first direction D1On multiple pixel column PR and layout
With first direction D1Second direction D intersected2On multiple pixel column PC.It is arranged in single
Multiple pixels in row are commonly referred to as pixel column PR, and the multiple pixels being arranged in single row
Commonly referred to as pixel column PC.
It is to say, when multiple pixels are arranged with m * n matrix form, " m " individual pixel column
PR1,PR2,PR3,...PRm-2,PRm-1,PRmIt is arranged in first direction D1On, and " n "
Individual pixel column PC1,PC2,PC3,...PCn-2,PCn-1,PCnIt is arranged in second direction D2On.
It addition, round-shaped in order to make viewing area DA present, form each pixel column PR
Pixel column PR from the central area CP of viewing area DA of the number of pixelm/2Towards aobvious
Show the pixel column PR at the marginal area EP of region DA1And PRmReduce.Similarly, shape
Become the number of pixel of each pixel column PC picture from the central area CP of viewing area DA
Element row PCn/2Towards the pixel column PC at the marginal area EP of viewing area DA1And PCnSubtract
Few.
But, although having pixel arrangement described above, but viewing area DA can
Can cannot obtain perfectly round shape.As it is shown on figure 3, in the marginal zone of viewing area DA
Territory EP, can be observed the hierarchic structure being made up of the multiple pixels being arranged to step structure.
Therefore, according to the present invention, the lid window 120 on display floater 110 is carried out optical design,
Make to prevent the visible of the hierarchic structure at the marginal area EP of viewing area DA or reduce it can
Degree of opinion, thus the display device that display quality improves relatively is provided.
Fig. 4 is the sectional view of the line I-II intercepting along Fig. 1.
With reference to Fig. 4, lid window 120 includes the center covering the central area CP of viewing area DA
The marginal portion 123 of the marginal area EP of part 121 and covering viewing area DA.Lid window 120
Marginal portion 123 with angle of chamfer (such as, predetermined angle of chamfer) θcIt is chamfered.
The available marginal portion 123 being chamfered of lid window 120 is totally reflected from being arranged in viewing area
The light that pixel at the marginal area EP of DA sends.Therefore, it is arranged in viewing area DA's
Pixel at marginal area EP can be sightless from outside, thus can prevent hierarchic structure
Visible or reduce its visibility.
It is to say, the light inciding the marginal portion 123 of lid window 120 utilizes marginal portion 123
Inclined-plane 123a can be totally reflected.
When the incident angle of the light inciding inclined-plane 123a is expressed as " incidence angle θi", and from
The transmitting angle of the light that inclined-plane 123a sends is expressed as " emission angle thetat" time, incide inclined-plane
The incidence angle θ of the light of 123aiWith angle of chamfer θcEqual, and the light sent from inclined-plane 123a
Emission angle thetatCan be about 90 degree or more than 90 degree, to allow to be totally reflected.
